Application filed January 24, 1924.

To all whom t may concern:

Be it known that I, BARNEY Nenn, a subject of the King of England, residing at Windsor, in the Province of Ontario, Dominion of Canada, have invented a new and useful Improvement in a Heel Attachment, of which the following is a specification.

My invention relates to a new and useful improvement in a heel attachment and has for its object the provision of an attachment adapted for mounting in heels whereby the user is afforded means of bringing into operation, at will, a device for preventing slipping.

Another object of the invention is the provision of a calli for preventing slipping so arranged in the heel of a shoe that it may be withdrawn from operative position at will, and locked in either operative or inoperative position.

Another object of the invention is the provision of a pointed member adapted to project from the surface of the heel of a shoe to engage the surface over which the user may be passing to prevent any undue slipping of the user.

Other -objects will appear hereinafter as the description proceeds and the features of theinvention are pointed out. i

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which,

Fig. 1 is a plan view of the invention with the cover removed,

Fig. 2 is a plan view Vof a heel with the invention attached,

Fig. 3 is a sectional View of the invention, taken centrally longitudinally thereof,

Fig. 4 is a transverse sectional view of the invention,

Fig. 5 is a sectional view taken on substantially line 5-5 of Fig. 4,

Fig. G is a sectional view taken on substantially line 6 -6 of Fig. 1 showing the pins in operative position,

F 7 is a plan view of a spring used in the invention, and,

Fig. 3 is a plan View of another spring used in the invention.

The invention is adapted for preventing the slipping of the person wearinga shoe in which the invention is mounted. 1 prefer to have the invention built into the heel of the shoe, although ,it may be embedded Serial, No. 688,204.

persons shoe in any manner longitudinally of the shell from the fori ward to the rearward end is a groove 15 which communicates with the pocket 13 yand with a pocket 16 formed at the opposite end of the shell. A T-shaped operating slide is positioned inthe groove adapted for slide able movement therein and provided with arms 13 which lie in the pocket y13 and with arms 19 which lie in the poclret 16. rFhe arms 19 are provided with an enlarged por* tion 19 having a beveled edge, as shown in Fig. 3.

The shell is provided with a pair of projections 20, at the forward end thereof, which, when the device is mounted in a heel 36, terminate substantially flush with the surface of the heel. Each of these projectionsr20 is provided with a bore 21 in which is snugly engaged, and adapted for slideable movement, pins 22, having sharpened outer ends and the inner ends provided with heads. These pins are projected through openings formed in a leaf spring 23, said opening being large enough to permit the projectiony of the body of the pins therethrough and to engage the heads of thev pins. This spring 23 is provided at each end with a tongue 24 and 24. After the pins are projected through the openings formed in the spring the spring is placed in the pocket 13, so that the pins 22 will engage in the bores 21. vWhen the spring is in its normal position, as shown in Fig. 4, the pins are retracted within the bores 21. The tongues 24 and 24 then engage against a shoulder 24" formed on the edge of the pocket 13. Each of the arms 13 is provided with an enlargement 37 which has a beveled edge and is adapted to engage the head of the pins 22 for forcing the saine downu wardly out of the bores 21 into the position shown in Fig. 5. When this projection is withdrawn so as to allow the withdrawal of the pins into the bores, as will be eX- plained herein, the projection lies in engagement with the tongue 24 or 24', so that its movement onto the elongated portion of the leaf spring 23 is easily accomplished.

At the rearward end of the shell there is provided an abutment or projection which, When the device is mounted on a heel, termina-tes substantially flush With the outer surface of the heel. This projection is provided With a pair of bores in which is snugly positioned for slideable movement a pair of the pins 26. rlhe pins 26 are projected through openings 26 formed in ak leaf sirino havinfT laterall eXtendinO` arms 27.

D D t3 A tongue 28 projects from one side of the center of these arms and a tongue 29 projects from the other side, the tongue 28 being elongated comparatively to the tongue 29. After the pins 26, which are of the same construction as the pins 22, are projected through the openings 26 the same are positioned in the bore formed in the projectioin 25, the leaf spring lying in the pocket 16. The tongue 29 normally is in engagement With the under surface of a projection 19 formed on the member 19. Then this projection is moved into the position shown in Fig. 3 the pin is retracted as shown and When moved into the position shown in Fig. 6 the pins 26 are projected as shown.

An extension of the member 17 is provided which extension 8O projects beyond the end of the shell and affords a means for pivotally attaching the operating handle or crank 31 thereto. This handle 31 is provided With a substantially circular portion and is attached eccentrically to the portion 30. rlhe shell is'provided with a n otchv 31 in which the circular portion rests when moved to its different positions, and by moving the handle from one side to the other the member 17, because of the eccentric mounting of the handle is caused to slide in the shell, thus bringing the portions 19 and the enlarged portions 37 which are formed on the parts 18 into engagement With the heads of the pins to force them outwardly of the shell against the tension of the springs.

in this Way the pins may be moved out of the shell or Withdrawn, the springs servingA to Withdraw them after disengagement with the enlarged portions 19 and 3'?.

l'laving thus described my invention What l claim as new and desire to secure by Letters Patent is:

1. An attachment for heels, comprising a, easing adapted for embedding` in a heel having a longitudinally extending channel formed therein and communicating adjacent one end With a transversely extending passage at opposite sides to form a cross-shaped recess; movable callrs mounted in said casing and adapted for projecting therefrom; a cross-shaped actuating member, slidably positioned in said channels having a crosshead at one end of its trunk, the arms and the cross-head of said cross-shaped member being adapted for engaging said calks for projecting their ends out of said casing into operative position, said cross-shaped member being slidably movable into operative or inoperative position.

2. An attachment for heels, comprising a casing adapted for imbedding in a heel, having a longitudinally extending channel formed therein and comn'iunicating, adjacent one end, With a transversely extending passage at opposite sides, to form a cross-shaped recess; movable callrs mounted in said casing and adapted for projecting therefrom; a cross-shaped actuating member, slidably positioned in said channels having a crosshead at one end of its trunk, the arms and cross-head of said cross-shaped member being adapted for engaging said calks for projecting their ends out of said casingr into operative position, said cross-shaped member being slidably movable into operative or inoperative position; and means exterior of said casing for moving said cross-shaped member into operative or inoperative position.

3. An attachment for heels, comprising a casing adapted for imbedding in a heel, having a longitudinally extending channel formed therein and communicating, adjacent one end, with a transversely extending passage at opposite sides, to form a crossshaped recess; movable calks mounted in said casing and adapted for projecting therefrom; a cross-shaped actuating member, slidably positioned in said channels having a cross-head at one end of its trunk, the arms and cross-head of said cross-shaped member being adapted for engaging said callrs for projecting their ends out of said casing into operative position, said crossshaped member being slidably movable into operative or inoperative position; means eX- terior of said casing for moving said crossshapcd member into operative or inoperative position; and resilient means attached to said callrs for normally retaining the ends of the same retracted into said casing.

In testimony whereof l have signed the foregoing.
